Applications
4WMME directional valve combines solenoid automatic control with emergency manual override function. It controls start‑stop and direction switching of hydraulic cylinders and motors.
It is widely applied in machine tools, mining machinery, hydraulic test benches and engineering equipment. Perfect for systems requiring normal electric control, meanwhile needing manual backup for power‑off emergency, on‑site commissioning and fault maintenance. Filtered mineral hydraulic oil is required to extend service life.
Factory&FAQ
4WMME Directional Valve are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
1. What is the 4WMME Directional Valve ?
4WMME directional valve is a solenoid‑actuated spool‑type hydraulic directional control valve fitted with emergency manual override. Normally it runs by solenoid for automatic control. When power fails, the built‑in manual push button enables emergency valve switching. Multiple spool functions and standard ISO subplate mounting are available to control hydraulic actuators for industrial and mobile hydraulics.
2. What makes the 4WMME Directional Valve ?
4WMME directional valve features dual‑control design: normal solenoid automatic operation plus built‑in emergency manual override. It enables manual valve switching under power‑off or fault conditions for commissioning and maintenance. Multiple spool functions are available. It adopts ISO standard subplate mounting, with low internal leakage and reliable high‑pressure performance for safety‑critical hydraulic systems.
3. What is the working pressure range of 4WMME Directional Valve ?
The maximum working pressure for P, A, B ports is 31.5 MPa, while the T return port is limited to 16 MPa. Stable performance can be achieved under rated pressure conditions for both industrial and mobile hydraulic working environments.
4. Can 4WMME Directional Valve replace other brands?
Yes, 4WMME directional valve can substitute most mainstream 4WMME‑series valves. It complies with ISO 4401 standard mounting dimensions. Compatibility depends on working pressure, spool function, coil voltage and emergency manual‑override structure. Please verify these key parameters before replacement. Custom solutions are available in case of structural differences.
5. What is the Response / Switching frequency of 4WMME Directional Valve ?
Under solenoid operation, its typical spool switching response time is 40‑80 ms. The emergency manual override is only for commissioning and power‑failure emergency use, not for frequent cyclic operation. Practical switching frequency depends on control signals. Oil viscosity and working pressure will influence spool movement performance.
